Abstract (en)
[origin: WO2009152628A1] The invention is substantially characterized in that, for access control, in a first step a wireless radio connection (expressly meaning not only radio frequencies, but also the communication by way of microwave frequencies or other frequencies of the electromagnetic spectrum) is established between the object to which access is sought and an access control medium (mobile telephone, other electronic device, chip card, and the like). By way of said wireless connection, first an authentication method is carried out, during which the access authorization of the access control medium is checked. Thereafter, a temporary access code is sent from the object to the access control medium and from there it is returned to the object, in some instances in modified form. For this purpose, the capacitive-resistive coupling is used either for returning the - optionally modified - access code to the object, or perhaps for sending the access code to the access control medium; the signal is sent in the respectively other direction by way of the wireless connection.
